discussion are explained in further details in Chapter 4. Finally, the thesis ends with Chapter 5 which concludes the overall project followed by a number of
recommendations for future work and research.
CHAPTER II
LITERATURE REVIEW
2.1 INTRODUCTION
This chapter covers a fully-referenced review based on the relevant literature as well as the basic theoretical concept of an energy efficient lighting system, the
concept of energy harvesting, and the research on the TEG. The chapter begins with the description of the existing domestic lighting systems, followed by studies on the
related theoretical review and energy harvesting. Then, it explains the theory of thermoelectricity which includes the Seebeck Effect, thermoelectric generator, and
the research on the existing work regarding the project. Finally, the chapter explains about microcontroller and Microchip‟s Peripheral Interface Controller PIC. At the
end of the chapter, a summary is provided.
